noun (pl) -bies

1.

a deep red transparent precious variety of corundum: occurs naturally in Myanmar and Sri Lanka but is also synthesized. It is used as a gemstone, in lasers, and for bearings and rollers in watchmaking. Formula: Al2O3

"clear rich-red variety of corundum," c.1300, from Old French rubi (12c.), from Medieval Latin rubinus lapis "red stone" (cf. Italian rubino), from Latin rubeus "red," related to ruber (see red). As a color name from 1570s. As an adjective from late 15c. Modern French rubis is not explained; Klein suggests a plural mistaken for singular.

1. A relational language designed by Jones and M. Sheeran in 1986 for describing and designing circuits (a hardware description language). Ruby programs denote binary relations and programs are built-up inductively from primitive relations using a pre-defined set of relational operators. Ruby programs also have a geometric interpretation as networks of primitive relations connected by wires, which is important when layout is considered in circuit design. Ruby has been continually developed since 1986, and has been used to design many different kinds of circuits, including systolic arrays, butterfly networks and arithmetic circuits.

A fully object orientedinterpretedscripting language by Yukihiro Matsumoto . Similar in scope to Perl and Python, Ruby has high-level data types, automatic memory management, dynamic typing, a module system, exceptions, and a rich standard library. Other features are CLU-style iterators for loop abstraction, singleton classes/methods and lexical closures. In Ruby, everything is an object, including the basic data types. For example, the number 1 is an instance of class Fixnum. Current version (stable): 1.6.7, as of 2002-03-01. Ruby Home (http://ruby-lang.org/). Ruby Central (http://rubycentral.com/).

(Heb. peninim), only in plural (Lam. 4:7). The ruby was one of the stones in the high priest's breastplate (Ex. 28:17). A comparison is made between the value of wisdom and rubies (Job 28:18; Prov. 3:15; 8:11). The price of a virtuous woman is said to be "far above rubies" (Prov. 31:10). The exact meaning of the Hebrew word is uncertain. Some render it "red coral;" others, "pearl" or "mother-of-pearl."
